Galaxies are huge groupings of stars, planets, gas, and dust. Our sun is in the MILKY WAY galaxy, which measures about 100, 000 light-years across. That long thin milky bright shape across the middle of the night sky is made up of about several billion stars in our galaxy. Our gal...
(Phys.org)—Astronomers have used NASA's Chandra X-ray Observatory to find evidence our Milky Way Galaxy is embedded in an enormous halo of hot gas that extends for hundreds of thousands of light years. The estimated mass of the halo is comparable to the
